I the city of New York, borough of Mam hattan, in the county and State of New York, have invented a new and Improved Boer-Frame Construction for Buildings, of which the following is a full, clear, and exact description, 7

The invention relates to a door frame construction for buildings. the invention-is to provide a simple, efficient, durable, strong frame construction which is composed of a minimum number of simple parts which act as a support for the plaster extending between it and the walls and ceiling of a room.

Another object concerns the provision of specific means whereby the connection between the supporting frame and the plaster is rendered unusually effective and simple.

A further object concerns the provision of means whereby the connection of the plaster support through the frame and the formation of the plaster body portion are rendered unusually simple and enables plaster to be applied much more easily and 1egconomically than hitherto has been possi- The invention is illustrated in the drawin s, of which igure 1 is a perspective view of a door frame in position with the plaster unit shown partly broken away;

Fig. 2 is a section through one of the vertical door frames, showing the relation of the parts before the plaster is applied to the support;

Fig. 3 is a section taken on the line 33 of Fig. 1; and

Fig. 4 is a similar section showing suita ble ornamental mold strips attached to the frame member.

The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and in the character of the materials used may be adopted without departing from the spirit of the invention as set forth in the appended claim.

In its general aspects the invention concerns the provision of a door-frame post of essentially three elementstwo vertical elements and one horizontal-forming a door f ame a d e h made f i gle Piece of An object ofmaterial such as wood; Preferably, each of the faces of these door frame elements, which abut the plaster support, is provided with a recess in which the plaster support is connected to' the frame and into which the plaster itself projects so as to form a very simple and yet strong joint between the frames and the plaster, and when so constructed no open seams are permitted between the plaster and thed oor' frame.

In its more specific aspect the invention contemplates sin-glei-pi'ec'e frame member the opposite outside edgesof which are usedfor the purpose of gaging the thickness of the plaster to be applied to this plaster support.

A further specific aspect of the invention contemplates the application of simple, ornamental mold strips to the frame elements, which act not only in an ornamental capacity but also more effectively render the joint between the frame and the plaster effective and tight.

In the pref-erred embodiment of the invention shown in the drawings, I provide a. simple door frame post of three frame members, 1, 1 and 1", forming two vertical and one horizontal member joined together in any suitable manner and preferably supported or connected to the floor of the frame. The. frame members are provided with projecting flanges 2 which are adapted to act as a stop for the door, which is suitably hung in this frame. The. face of each of the frame members to which the plaster support is connected is provided with a groove or recess 3 in which are suitably mounted a plurality of plaster-supporting engaging elements such as hooks. A plaster support 4 is connected to these hooks, or other suitable engaging elements, and extend between the door frame and the floor, the walls and the ceiling of the room. This plaster support may be of any suitable-type wire mesh fabric or the like. After the frame is mounted and the plaster support is connected thereto, the plaster 5 is applied to the support in any desired manner until the thickness of the plaster lines up with the opposite lateral edges of the frame elements. In this manner, therefore, the opposite edges of the frame elements act as gages or guides to determine the thickness of the plaster, which must be finished flush with these edges,

In the modificati n sho n n F gt may be desirable to provide the opposite lateral faces of the frame members with grooves such as 6 and 7 into which portions of ornamental mold members 8 and 9 are adapted to project. These mold members extend, preferably, rearward of the frame member along the plaster a short distance to more effectively make the joint between the plaster and the frame a tight one. It will be observed that by allowing the plaster to extend into the groove 3 it will be impossible for any open seam to be formed between the plaster and the frame which will enable a person to look between the frame and plaster from one room into another.

It will be observed from a consideration of Figs. 1, 2 and 3 that the entire construction, including the door frame and plaster support, comprises only four elements, namely, the three frame elements and the plaster support; and that in the modification shown in Fig. 4 only two additional elements are added, namely, the ornamental mold strips 8 and 9. This construction will permit the door-frame elements to be of substantial dimensions so as to form a strong, rigid frame to which the plaster support can be connected, and it is found that when the plaster is applied to this support and hardene d the entire assemblage is strong and firm.

What I claim is In combination, a door frame element comprising a single piece of wood having a groove in one face into which a tongue of plaster is adapted to project, the lateral edges of the element providing a gage for the thickness of the plaster, said element also having lateral grooves, a pair of mold strips adapted to lie in said lateral grooves and having portions projecting beyond the end ofthe element to overlap the joints between said element and the plaster.
